Jin state was an early Iron Age state which occupied some portion of the southern Korean peninsula during the 3rd and 2nd centuries BCE, bordering the Korean kingdom Gojoseon to the north. Its capital was somewhere south of the Han River. It preceded the Samhan confederacies, each of which claimed to be successors of the Jin state.
